MEANS FOR MOUNTING RAILS ON CONCRETE FOUNDATIONS.

Application filed July 24, 1920. Serial No. $98,626:.

To (all whom it may concern Be it known that I, JoHN l3. Lo'r'r, a citizen of the United States, and resident of Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Means for llounting Rails on Concrete Foundations, of which the following is a specification.

My invention relates to improvements in devices employed for mounting railway rails on longitudinally disposed concrete ties or rail foundations, and it is especially designed as an improvement upon similar devices described in my prior patents dated December 19, 1911, and August 8, 191.6, and numbered 1,011,978 and 1,193,573 respectively.

As defined in general terms both of my prior patents contemplate mounting a single cushioning element between the base of a rail and the top of its concrete foundation, and the rail and cushioning element are fastened directly to the foundation by bolts anchored therein. My present invention, however, not only an improvement upon "my former attaching means for the rail, but

it is especially designed to provide means for preventing lateral movement of a rail with respect to its foundation or tie, and to provide what may be termed a double cushion between the rail and its foundation or tie.

More specifically, the principal objects of my present invention are; to provide cushiouedbase plate having longitudinal guard flanges for preventing lateral movement of a rail mounted therebetween; to provide means for anchoring the base plate in the 'l munlation and positively, but removzbly scouring the same thereto; to provide unitary means for primarily securing a rail in place between the guard flanges the base plate and secondarily serving as an attaching element for maintaining the base plate securely upon a foundation; and to provide a cushioning element between the rail and the base plate for absorbing in conjunction with the first mentioned cushioning element excessive vibration. due to the passage of rolling stock over the rails.

To these and other ends, my invention consists in the construction, arrangement and combination of parts described hereinafter and pointed out in the claims.

The preferred embodiments of my invention are represented by way of example in the accompanying drawings, where Fig. 1. is a scctiona-lview of the preferred embodiment of my invention;

Fig. 2, a top plan view of the embodiment illustrated in Fig. 1;

Fig. a detail perspective of the base plate;

Fig. 1, a sectional view showing a slight modification of the concrete foundationor tie and attaching means for the base plate disposed thereon; and

5, a modified form of base plate which is formed with a. portion thereof serving as an anchor embedded in the concrete. foundation.

Like characters of reference. designate like or similar parts throughout the several views of the drawings, in which A designates a longitudinal concrete rail foundation or tie similar in construction to that described in my prior Patent No. 1,011,978, and which in the present instance is formed with a longitudinal groove or channel 1 designed for the reception of an anchoring flange 2 formed on the base of the base-plate 4%. Between the base-plate el and the top of the foundation A is disposed a cushioning member 5 of wood or other suitable material, and upon the upper face of the base plate are formed a pair of complementary, parallel guard flanges 6 having sloping exterior sides '7. Carried between the guard flanges 6 is a second cushioning member 8 upon which is mounted a railway rail B. In the present instance the rail B is formed with suitable openings in its base for receiving securing bolts 5) which pass through the base 3 of the base-plate 4 and. the cushioning member 5 into the concrete fouudatitm A where their ends are hooked and embedded to securely hold them in place. It will be noted that the bolts 9 serve lo hold all of the foregoing elements assembly, but to insure against pos. ble loosening or displacement of the base-plate 4 other stay bolts 10 are provided which extend into engagement with tic-plates 11 mounted across the bottom of the foundation A.

In order to remove the rails and other elements including the base plates and cushioning members it is merely necessary to remove the nuts from the bolts 9 and 10, but when the road is set up possible loosening or spreading of the rails is positively prevented. and furthermore. the rail cushioning members 8 and the bolts 9 together with the base llO of the rails are protected by the guard flanges 6 on the base-plates.

In the slight modification illustrated in Fig. i, the construction of the cushioning members, base plate, guard flanges, and rail securing bolts is the same as in the preferred embodiment, but the concrete foundation or tie A is formed with lateral extensions 12. These extensions 12 serve to increase the breadth of the top of the foundation which in the present embodiment is cut away as at 13 to form a seat for the cushionin member and base-plate 4:. Furthermore, the bolts in the present instance are mounted in the extensions 12 thus eliminating the use bit"- plates 11 as in. the preferred embodiment of the invention.

The embodiment of the invention as illustrated in 5 contemplates forming the base-plate 4: with an enlarged base 1a which is embedded in the concrete foundation as illustrated, and has formed therein a pluralty of openings 15 and ribs 16 in and about Which the concrete sets to firmly anchor the base-plate in position. The bolts 9 in this modification are not anchored in the concrete as in the previous embodiments but are screwed directly into the base plate, and the use of a cushioning member between the foundation and base plate (as in Figures 1, 2, 3 and 4) is dispensed With.

The railroad construction contemplated in my present invention is particularly adapted to crossings, Where vehicle traffic must be contended with as Well as the usual rolling stock, for the usual cross-ties of wood become quickly WOIIl out and the continual jolts delivered on the rails by Wheels quickly cause loosening and spreading of the rails. Furthermore Where longitudinal concrete foundations are in common use the method of securing the rails thereon is a decided improvement over the securing means heretofore used. Attention is also particularly called to the fact that the securing means for the rails as contemplated in the present invention is applicable to use with the road bed and foundation construction described in my prior Patents Nun'ibcrs 1,011,978 and 1,193,573.

While in the foregoing, there has been illust "ated in the d 'awings and described in the specification such combination and ar rangement of elements as constitute the prefcrred embodiments of this invention, it is nevertheless desired to'emphasize the fact that interpretation should only be conclusive when made in the light of the sub'joined claims.

Having described my invention and its objects With such attention to detail as will thoroughlyacquaint one skilled in the art with its construction and advantages 1 claim 1. Means for mounting rails on concrete foundations, comprising a base plate, means integral with the base plate on each side of a rail preventing lateral movement of the rail with respect to the plate, and separate means anchored to a concrete foundation and extending through the rail base to secure the rail against vertical upward movement with respect to said base plate.

2. Means for mounting rails on conc foundations, comprising a base plate, mt formed on the base plate for anchoring same to a concrete fornication, means i-' gral with the base plate on each side of a r preventing lateral movement of the rail respect to the plateand separate mean tending through the rail base for min the rail against upward moi-'ement spect to'the base plate.

3. Means for mounting-rails on concrete foundations comprising a base plate, means formed on the base plate for anchoring the same to a concrete foundation, cushioning members disposed above and below the base plate, and extending through the cushioning bers and base plate for attachin a rail thereto.

hhleans for mounting rails on concrete foundations comprising a base plate, a flange formed on the base plate for anchor-hag the same to the concrete foundation, a cushioning member between the base plate and foundation, a cushioning member carried be tween a rail and the base plate, and means formed on the base plate for guardi? preventing lateral movement of a respect to the base plate.
